Abstract

Selon l'invention, des câbles (22) sont formés en effectuant une pluralité de découpes (14) dans une face d'extrémité (12) d'un matériau stratifié (10) constitué d'un matériau conducteur. Une matière première (16) avec une partie en forme de peigne (26) dont les dents sont des câbles est formée à partir du matériau laminé. Les câbles (22) sont connectés les uns aux autres par la section base (24) de la partie en forme de peigne. La matière première (16) est pliée ou roulée dans une direction orthogonale aux câbles pour constituer un faisceau de câbles (34). La section base (24) de la partie en forme de peigne est coupée pour créer un faisceau de câbles (38) dans lequel chaque câble est formé indépendamment.
